TRUSSlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 613,247, dated November 1, 1898. Application filed December 24, 1897. Serial No. 663,367. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT CoLLEN, engineer, a subject of the Queen of Great Britain and Ireland, residing at 30 Pigott street, Limehouse, in the city of London, England, have invented certain Improvements in Truss ing-Machines,of which the following is a specification.

This invention relates to trussing-machines of the type known as open-trussing machines, in which the staves are contracted or forced together by the aid of trussing-hoops preparatory to their being more tightly forced together in what are known as close-trussing machines.

I will describe the invention by reference to the accompanying drawings, in which- Figures 1 and 2 are respectively a front and a side elevation of one of my improved trussing-machines.

The main framing of this machine consists of a base A, two standards or guides B B secured at their lower ends to the base, and a girder O, secured to the upper ends of the guides B B The hydraulic cylinder D is rigidly secured to the girder O, and the piston-rod D issuing therefrom, is secured to a fork or yoke E, connected to blocks E capable of sliding vertically in the guides B B In the blocks E (in accordance with a separate application for Letters Patent of even date herewith) is pivoted a reversible head or double cone F, by which the upper ends of the staves are forced together, and the two trussing-hoops contained in the said head are passed over these stave ends. My present improvements, however, may, if desired, be used in conjunction with a single or non-reversible cone. The two ends of the cylinder D are connected by pipes d 01 respectively, with the ports g 9 Fig. 2, of avalve G,which is constructed, preferably, like an ordinary D slide-valve, the movable valve of which may be operated to throw either of the said ports into communication either with the inlet g connected with the pressure-supply apparatus, or with the exhaust g, which is connected with a tank H, supported on the girder C. The valve G may be operated through a link 9 a lever g, pivoted in a standard 9 a rod g and a hand-lever g pivoted to the before-mentioned guide B The rod g passes through a bracket e,.secured to the block E, which slides in the guide B and on the rod 9 is provided an adjustable collar 9 with which the bracket 6 en gages,and thereby cuts off the supply of pressure-water when the cone F has ascended sufficiently to admit of the casks being inserted into or removed from the machine. The collar g is adjusted on the rod 9' to suit the different heights of the casks to be operated upon, so that the pressure-water may not be wasted by employing it for raising the cone beyond the necessary height.

To the before-mentioned pipe at is connected a pipe 01 which extends down to near the bottom of the tank H, at which part it is provided with a suction-valve 0Z which closes when exposed to the influence of the pressure-water-that is to say, when the pipe 61 is in communication with the supply-pipe 9 The valve d opens when the communication between the pipes d and g is broken and the communication between the pipes d and g is established, so that the cone F and the parts directly connected therewith may de scend by gravity, the water during this operation passing from the tank H through the pipes d and d into the upper end of the cylinder and from the lower end of the cylinder into the tank by way of the pipes d and g When the cone F has descended to the part of its travel at which it is required to force the staves together, the attendant raises the hand-lever g and thereby allows the pressure-water to enter the upper part of the cylinder to enable the cone to complete the short remaining portion of its downward stroke.

At its upper part the tank H has connected to it a pipe h, which may conduct the water which overflows from the said tank back to the waste-water tank, from which the pumps or other pressure-generating devices draw their supply. The tank H also has an airinlet at h to prevent the formation of vacuum. To prevent any water which may leak through the stuffing-box d of the cylinder D from descending onto the casks, I provide the yoke E with a cup e to which is connected a pipe a which conducts the said water to the side of the machine, where it may be de' livered into any desired receptacle.

Although I have shown the tank H at the IOO side of the cylinder D, Which is the most suitable position for it, I may arrange it either higher or lower than the said cylinder.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is 1. In a trussing-machine the combination with a cone and a frame with vertical guides for the cone, of an inverted hydraulic cylinder on the frame, a piston in the cylinder connected to the cone, a tank, a pipe connecting the cylinder-exhaust with the tank, a pipe connected with the upper end of the cylinder and dipping into the tank, a valve on the end of this pipe, an overflow-pipe for the tank, a
